This invention relates to the use of adthe adjustable cross-bar limiting the tearing hesive tape in surgery,and'in'ore particularly of the strip, Fig. 9 isa longitudinal section of strips of such adhesive material as ripped of the same, showing theconstruction of the iroma wide sheet thereof.

For the winding of the spring to produce the desiredtensionon the:

and will snap it back to normal position as soon as the strip is severed. In practice,

The operation of detaching a stripcof hesiv e material is simple and evident. With a finger the operator peeIsup atthe-top of the a I adherent sheet astrip as wide as desired, and
